Toall'whomitmay concern." 7 thus prevents the escape of these gases Be it known that I, WILLIAM Hownnn through the relatively lar clearance space Lrvmqs, 'asubject of the King of Great between the mortar and t e bomb; in this Britain, resid-m at Hampstead, London, manner it is possible to obtain lon r ranges of the charge box' showing the method of I 25 1 inset-which m be ,mrr unded ignition charge;-

by a tempo alpparatus-is more particularly designed for t e gas simultaneous sa vos.

oneiof-the bags 40 England',,r h ave invented a new and useful Improvement in Mortars, of which the following i a specification. This invention relates to a mortar and 'ally to an im roved charge box whieh enables c arges to' be thrown and longer to be 0 tained, particiilarly are unes unturned. ,5, The

a is. gas-check combined with a tin box b ,fonininfithe container or char box for the prope en't charge, which ma be of flake eordite or other suitable pro 11] "t.

, Whenloaded-in the mortar e electric leads 0 connected to the box pass along the from the tively la clearance stglace betweeh the bore and e' bomb'and rough holes as e inthe flange f of-the steelfis checlria. into g .of co te-or powder forming the pro llentcharge where an-electrical1y fired I shaped eckreeeivingtheend of lid 5..

I

The .short chamber at the base end is fitted with a screw plug and' has cross holes m, by which the li'illld is introduced into the bomb; the ong'er end is packed with the burstingcharge and takes the gaine o and the fuse p.

It is obvious therefore into two that the gas-check and ed 1 charge box ,(whichallow bombs to be used with more than 3% clearance, e., d'ifierence in diameter between the bomb and the mortar tube) can be used with bombs of other construction for still larger ran es and higher pressures than those for'w ich the foiagoin as described is designed. n at claim is:

the combination with a chargebox, of a M an s-check attached thereto,"and an electric lead withinthe mortar and running from the muzzle to the char box.

6., A charge box having a fi anged cupshaped as-check attached thereto, an electric lea connected to a fuse in'the charge box and a lid'fitting the flange of the gascheck.

In testimony that I' claim the foregoing as my invention I have signed my name this 31st da of Jul 1918.
